To furnish a reliable basis for the revision of the guide values on manure production and composition of fattening beef cattle, 37 balance experiments were conducted on 13 Swiss farms. The daily growth rate of the animals varied between 1100 and 1500 grams. The mean annual production of slurry per fattening beef place was 7.5 t of fresh matter and 0.65 kg of dry matter. For solid manure systems it was 6.8 t of fresh and 1.2 t of dry matter. The mean annual excretion per fattening beef place was 38 kg nitrogen, 13 kg phosphate (P2O5) and 39 kg potash (K2O). Apart from the phosphate excretion and the amount of solid manure, which were both significantly lower, these results correspond well with the present Swiss guide values. Only on few farms there was a significant potential of reducing the copper and zinc content of the manure by reducing the amount of these elements in the ration.
Grass-based beef production is markedly less productive than intensive year-round indoor-housing system-based production. Agroscope experts therefore studied how grass-based farms can produce both economically and in an ecologically sound manner.
Orchard crop spraying using unmanned aerial spraying systems commonly referred to as drones can lead to drift, posing a risk to residents and bystanders. The study shows that the risks arising from this are taken into account by the current registration process.
Trials conducted by FiBL have shown that conversion to organic farming also promotes endangered Red List species such as the carabid beetle species Amara tricuspidata. This species and other species consume seeds of forbs and grasses and thus supports natural weed control.
